# TaskJuggler::RealFormat

This class provides the functionality to format a Float according to certain rules. These rules determine how negative values are represented, how the fractional part is shown and how to structure the mantissa. The result is always a String.

The class uses the following parameters to control the formating. signPrefix: Prefix used for negative numbers. (String) signSuffix: Suffix used for negative numbers. (String) thousandsSeparator: Separator used after 3 integer digits. (String) fractionSeparator: Separator used between the inter part and the

    fractional part. (String)

fractionDigits: Number of fractional digits to show. (Fixnum)

### Attributes

fractionDigits[R]
fractionSeparator[R]
signPrefix[R]
signSuffix[R]
thousandsSeparator[R]

### Public Class Methods

new(args) click to toggle source

Create a new RealFormat object and define the formating rules.

    # File lib/taskjuggler/RealFormat.rb, line 32
    def initialize(args)
      iVars = %( @signPrefix @signSuffix @thousandsSeparator
                  @fractionSeparator @fractionDigits )
      if args.is_a?(RealFormat)
        # The argument is another RealFormat object.
        iVars.each do |iVar|
          instance_variable_set(iVar, args.instance_variable_get(iVar))
        end
      elsif args.length == 5
        # The argument is a list of values.
        args.length.times do |i|
          instance_variable_set(iVars[i], args[i])
        end
      else
        raise RuntimeError, "Bad number of parameters #{args.length}"
      end
    end

### Public Instance Methods

format(number) click to toggle source

Converts the Float number into a String representation according to the formating rules.

    # File lib/taskjuggler/RealFormat.rb, line 52
    def format(number)
      # Check for negative number. Continue with the absolute part.
      if number < 0
        negate = true
        number = -number
      else
        negate = false
      end

      # Determine the integer part.
      intNumber = (number * (10 ** @fractionDigits)).round.to_i.to_s
      if intNumber.length <= @fractionDigits
        intNumber = '0' * (@fractionDigits - intNumber.length + 1) + intNumber
      end
      intPart = intNumber[0..-(@fractionDigits + 1)]
      # Determinate the fractional part
      fracPart =
        @fractionDigits > 0 ? @fractionSeparator +
                              intNumber[-(@fractionDigits)..-1] : ''

      if @thousandsSeparator.empty?
        out = intPart
      else
        out = ''
        1.upto(intPart.length) do |i|
          out = intPart[-i, 1] + out
          out = @thousandsSeparator + out if i % 3 == 0 && i < intPart.length
        end
      end
      out += fracPart
      # Now compose the result.
      out = @signPrefix + out + @signSuffix if negate
      out
    end

to_s() click to toggle source

    # File lib/taskjuggler/RealFormat.rb, line 87
    def to_s
      [ @signPrefix, @signSuffix, @thousandsSeparator, @fractionSeparator,
        @fractionDigits ].collect { |s| "\"#{s}\"" }.join(' ')
    end
